A chondroma is a benign cartilaginous tumor, which is encapsulated with a lobular growing pattern.

Tumor cells (chondrocytes, cartilaginous cells) resemble normal cells and produce the cartilaginous matrix (amorphous, basophilic material).

Characteristic features of this tumor include the vascular axes within the tumor, which make the distinction with normal hyaline cartilage.

Based upon location, a chondroma can be described as an enchondroma or ecchondroma.

enchondroma - tumor grows within the bone and expands it.
ecchondroma - grows outward from the bone and this is rare.

Treatment - best left alone - if it causes fractures (enchondroma) or is unsightly it should be removed by curettage and the defect filled with bone graft. ^[1]

18-year-old woman with a dural mass.

Somerset H, Wilkinson CC, Kleinschmidt-Demasters BK.AbstractWe report a case of a dural-based chondroma in the right frontal extra-axial region. Chondromas are benign cartilaginous tumors which are uncommon intracranially. Their diagnosis should be predicated on the exclusion of a chondrosarcoma and clinical studies should be performed to rule out any underlying tumor predisposition syndromes.

Subungual atypical fibroxanthoma is a rare mesenchymal skin tumor of intermediate malignancy. It classically presents as a relatively nondescript, erythematous nodule; it may ulcerate and bleed, but pain and pruritus are uncommon. In the differential diagnoses of subungual tumors, glomus tumor, soft
